Medicare allowed amount for participating (non-QP) physicians, before deductible, coinsurance and claim adjustments. Not a patient’s bill or a hospital charge.

What 22634 covers

This code captures each additional lumbar disc space fused after the first when the surgeon combines a posterior or posterolateral fusion with an interbody fusion performed from the back. The surgeon prepares the disc space and performs interbody fusion while also creating a posterior or posterolateral fusion at that level. Laminectomy or discectomy performed to prepare the interspace is part of the service. Spine surgeons typically report it for multilevel lumbar fusion operations in hospital or ambulatory surgical settings.

Report 22634 for each additional interspace treated with the combined technique beyond the initial level represented by 22633. It is an add-on code and must be billed with that primary procedure; it is paid within the primary procedure's global period. The operative report should identify each fused interspace and document both fusion techniques at each additional level. Count interspaces, not vertebrae or implants.
